Abstract
Magnetic sphincter augmentation (MSA) is a successful treatment option for chronic gastroesophageal reflux disease; however, there is a paucity of data on the efficacy of MSA in obese and morbidly obese patients. To assess the relationship between obesity and outcomes after MSA, we conducted a literature search using MeSH and free-text terms in MEDLINE, EMBASE, Cochrane and Google Scholar. The included articles reported conflicting results regarding the effect of obesity on outcomes after MSA. Prospective observational studies with larger sample sizes and less statistical bias are necessary to understand the effectiveness of MSA in overweight and obese patients.
